Artificial Sweetners in Groundwater Signal Contamination from Septic Systems
Researchers have determined that the presence of artificial sweeteners in rural groundwater is evidence of local septic system wastewater contamination.
China Introduces Massive Island-building Vessel
The boat is expected to be operational in June 2018 after completing a final round of tests.
Safer Water Using UV Light
Inspired by an experience involving contaminated well water in her rural Kentucky hometown, Ph.D. student Natalie Hull is exploring the different wavelengths of ultraviolet radiation needed to kill dangerous drinking water pathogens.
Video: Advanced Control of Wave Energy Converters
Modeling and experimental studies have resulted in a control system that doubles power system output while reducing electricity generation costs.
Corvus Energy to Power Industry’s First Hybrid Fish Farm Processing Vessel
Corvus Energy has been selected by Wärtsilä to supply a lithium ion-based energy storage system for the world’s first full service hybrid fish farm processing and transport vessel.
Collaborative Robotics Driving Manufacturing Productivity Gains
Automation can help improve process quality, consistency and throughput by allowing robots to perform repetitive, boring or unsafe tasks while humans engage in operations that require their superior cognitive abilities, skill and judgment.
Chile Taking Steps to Ban Plastic Bags in Coastal Regions
With an estimated 8 million tons of plastic being dumped into the sea each year, Chile’s President Michelle Bachelet signed a bill that will aim to ban plastic bags in over 100 coastal towns and villages.
Freshwater Generator Cuts Power Consumption by Almost 70%
The generator maximizes energy efficiency and capacity-to-footprint ratio by making use of the vessel’s existing seawater cooling system pumps.
Norton MilliNium Wheels Roll Bottom-Line Benefits
Norton R & D engineers developed MilliNium™ grinding wheels that provide longer life and material removal rate improvements over existing hot-mill-roll grinding solutions.
Jumping Nanoparticles Improve the Understanding of Friction and Thermal Motion
By monitoring the motion of the nanoparticle over time, the scientists determined the rate at which the nanoparticle hops between the wells for a wide range of friction that can be accurately tuned by adjusting the pressure of the gas around the nanoparticle.
Joint Development to Improve Hurricane Forecast Accuracy
Two government agencies of France and China are developing CFOSAT (China-France Oceanography SATellite) with hopes of using the data to improve hurricane and cyclone forecast accuracy in years to come.
ICCT Study Finds GHG Emissions from Shipping on the Rise
Carbon dioxide emissions from global shipping (oceangoing vessels, domestic ships and fishing vessels) increased from 910 to 932 million tons during 2013-2015.
SeaWalk Offers Cruise Lines Larger Ships and More Remote Ports of Call
Docks or piers are not always available at the new or deeper ports of call that are increasingly required for larger cruise ships. SeaWalk™ self-propelled floating piers has been deployed at many of these ports as they offer lesser environmental impacts, lower cost, and faster installation time.
Engineers Claim Breakthrough in Offshore Wind Construction
University of Delaware researchers say that their process could cost up to $1.6 billion less per project than conventional approaches and take half the construction time.
Testing Methods to Reduce Cargo Ship and Blue Whale Collisions
With enormous cargo ships responsible for killing nearly 80 endangered blue whales a year off of the United States Pacific coastline, a group of marine scientists have been tasked with a year-long mission to explore possible solutions to prevent the often fatal collisions.
Disinfectant Wipes Out Legionella From Hospital Water Supply
Using a pH neutral electrochemical solution (minus toxic chemicals) in combination with the patented membrane electrolytic reactor system, Ecas4 was able to create water safe for drinking, cleaning and manufacturing.
Wastewater Testing Could Give Early Warning System for Preventing Epidemics
Experts from the University of Bath and Stellenbosch University, South Africa, are jointly developing a notification system to alert communities to concerns with sewage systems.
Wave Energy Generator Starts Sea-Based Tests
A wave energy generator designed to power approximately 5,000 homes has entered sea testing stage.
New Study Reveals Invasive Plant Removal Can Improve Biodiversity in Streams
Removing invasive species will not only impact native plant species but will also impact aquatic organism biodiversity in nearby streams, according to recent research.
A Possible Solution to the Offensive Odor of Wastewater Treatment
Using common and inexpensive chemicals, researchers discovered a possible solution to the toxic and smelly anaerobic digestion (recovering energy and nutrients from wastewater sludge via microorganisms fermenting organic waste) process often used in wastewater treatment facilities.
